Characterization Of Glycated Proteins By 13C Nmr Spectroscopy, Carolyn I. Neglia, Helga J. Cohen, Albert R. Garber, Suzanne R. Thorpe, John W. Baynes

Faculty Publications

13C NMR spectroscopy has been used to characterize Amadori (ketoamine) adducts formed by reaction of [2-13C]glucose with free amino groups of protein. The spectra of glycated proteins were acquired in phosphate buffer at pH 7.4 and were interpreted by reference to the spectra of model compounds, N alpha-formyl-N epsilon-fructose-lysine and glycated poly-L-lysine (GlcPLL). The anomeric carbon region of the spectrum (approximately 90-105 ppm) of glycated cytochrome c was superimposable on that of N alpha-formyl-N epsilon-fructose-lysine, and contained three peaks characteristic of the alpha- and beta-furanose and beta-pyranose anomers of Amadori adducts to peripheral lysine residues on protein (pK alpha approximately …

Efficacy Of Three Anticoagulant Rodenticides For The Control Of Poison-Shy Rattus Rattus, Devendra Bhardwaj, Ishwar Prakash

Proceedings of the Eleventh Vertebrate Pest Conference (1984)

House rats (Rattus rattus) which do not consume a lethal dose of zinc phosphide develop poison-shyness after a single exposure. The surviving poison-shy rats cannot be baited again with zinc phosphide for about three months. Poison-shy rats were separately given anticoagulant baits (brodifa-coum 0.005%, coumatetralyl and warfarin 0.025%) in no-choice tests. The first two anticoagulants were found to be the most efficient ones. It was observed that those R. rattus which had consumed 56.7 mg/kg or more zinc phosphide died sooner (P < 0.05 to 0.1) after anticoagulant poisoning when compared with normal rats. It is conjectured that prothrombin inhibition is accelerated in the liver of poison-shy R. rattus due to the action of phosphine present in the earlier ingested sublethal dose of …

Nuisance Bats: Current Technology In Their Management And Control, Robert L. Corrigan

Proceedings of the Eleventh Vertebrate Pest Conference (1984)

Managing nuisance bat colonies can be accomplished via exclusion (bat-proofing) or in limited cases via the use of repellents. Exclusion is emphasized as the first and most desirable approach providing it is also practical. New products and devices have recently become available which may significantly aid in making exclusion programs more possible and practical. Repellents such as lights, fiberglass batting and various improvised mechanical devices may all have some utilization. Controlling nuisance bats can be accomplished via the use of toxicants and trapping, although there is considerable opposition from many bat researchers towards the use of toxicants. Toxicants that have …

Commingling Of Norway And Roof Rats With Native Rodents, Rex O. Baker

Proceedings of the Eleventh Vertebrate Pest Conference (1984)

The ecology of plague relies on the intermixing (commingling) of animal hosts and their ectoparasites. There has been a noticeable increase in commingling of rats and ground squirrels in Southern California in recent years. This paper discusses this phenomenon in Los Angeles and Orange Counties, where it occurs, how it results from man's activities, and the ecology of varying locations. The role of fleas as vectors of plague and the intermixing of fleas between hosts are discussed. Action to reduce the incidence of commingling and the threat of plague to the urban society is addressed.

Hazards To Golden-Mantled Ground Squirrels And Associated Secondary Hazard Potential From Strychnine For Forest Secondary Pocket Gophers, R. Michael Anthony, Gerald D. Lindsey, James Evans

Proceedings of the Eleventh Vertebrate Pest Conference (1984)

Radio telemetry and capture-recapture techniques were used to evaluate the hazards to golden-mantled ground squirrels ( Spermophilus lateralis) from hand baiting with 0.5% strychnine-treated for western pocket gophers (Thomomys mazama) on conifer plantations in eastern Oregon. Toxicology data were collected on field-killed and caged ground squirrels and on caged mink (Mustela vison, great horned owls (Bubo virginianus), and red-tailed hawks (Buteo jamaicensis). Ground squirrel populations were reduced 50% to 75% following underground baiting for pocket gophers. Maximum amount of strychnine found in cheek pouches and carcass of a field-killed golden-mantled ground …

Preliminary Investigations Of The Effectiveness Of Trimethacarb As A Bird Repellent In Developing Countries, R.L. Bruggers, P. Sultana, J.E. Brooks, L.A. Fiedler, M. Rimpel, S. Manikowski, N. Shivanarayan, N. Santhaiah, I. Okuno

Proceedings of the Eleventh Vertebrate Pest Conference (1984)

Preliminary information on the effectiveness of trimethacarb as a bird repellent on broadcast seed and ripening crops was obtained during 1982 and 1983 from studies in Haiti, India, the Philippines, Bangladesh, Mali, and the United States. R50 and LD50 determinations for nine pest bird species to cereal crops in these countries indicated birds were not as sensitive to trimethacarb as to the avian repellent methiocarb. Rice and millet seed germination was not inhibited at 0.125 and 0.25% treatment levels. Wheat seed germinated well at treatments of ≤0.5% in Bangladesh. Sorghum seed did not germinate as well at any treatment level. …

Keynote Address—Politics Of Pesticides, David H. Dietz

Proceedings of the Eleventh Vertebrate Pest Conference (1984)

The politics of pesticides is a rather humorless topic, as I'm sure most of you know. I've always been told that when you start an address or make a speech you ought to have some kind of humor, if for no other reason that you at least get your audience to listen to you for two minutes during any presen-tation. For those of you that may be members of the Audubon Society or members of the Sierra Club, I'll, in advance, make my apologies for the joke I'm about to tell. It's not really meant as a put down if …

Rat Control In Alberta, Michael J. Dorrance

Proceedings of the Eleventh Vertebrate Pest Conference (1984)

A rat control program, administered and coordinated by Alberta Department of Agriculture, has kept Alberta essentially free of Norway rats (Rattus norvegicus) since 1950. A control zone, 29 x 600 km, along the eastern border prevents rats from moving into Alberta from the east. Sporadic rat infestations within the interior of Alberta are reported by concerned citizens and eradicated by government personnel. Strong support for the program by citizens and local governments was developed through public education and information. The program has been successful for a variety of reasons including geography, climate, legislation, availability of warfarin, the relatively …

Success In Rat Control In Kuwait, K.S. Al-Sanei, T.M. Zaghloul, A.M. Salit, M.T. Omar, M.M. Balba

Proceedings of the Eleventh Vertebrate Pest Conference (1984)

The preliminary rat survey prior to the actual attack phase of Rat Control Program in Kuwait revealed an infestation rate with the Norway rat, Rattus norveqicus, in buildings ranging between 32.7% and 70.7%. The comparatively high infestation was observed in 92.5% of Kuwait buildings. Moreover the infestation reached 99% in certain districts of the country. This high infestation was associated with an increase in rat-borne diseases particularly murine typhus, salmonellosis, rat-bite fever and certain parasitic diseases.

A programme for rodent control in Kuwait was initiated through a political decision by the cabinet which gave the full responsibility of rodent …

Repellent Or Aversive Chemicals In Sheep Neck Collars Did Not Deter Coyote Attacks, Richard J. Burns, Guy E. Connolly, Richard E. Griffiths Jr.

Proceedings of the Eleventh Vertebrate Pest Conference (1984)

Since 1974 the Fish and Wildlife Service has studied a "toxic collar" to poison coyotes that attack collared sheep and goats. The collar patent (McBride 1974) indicates that the same collar could deliver chemicals to repel coyotes, thus saving both the coyote and the livestock.

This report summarizes our experience with nonlethal tests of collars. During collar tests with 10 different toxicants, 21 coyotes received sublethal doses followed by aversive behavior or potentially aversive reactions. The subsequent predation history of these coyotes was examined for prey-avoidance. After a sublethal test, all coyotes killed lambs or kids in about 40 days, …

Opening Remarks—Eleventh Vertebrate Pest Conference, Dell O'Clark

Proceedings of the Eleventh Vertebrate Pest Conference (1984)

On behalf of the Vertebrate Pest Council, it is my pleasure to welcome all of you to Sacramento and to the 11th Vertebrate Pest Conference. The first Vertebrate Pest Conference was held 22 years ago here in Sacramento in 1962. The conference is now over two years into its third decade of existence. In all this time, the basic goals of the Conference have not changed; that is, to provide a basis for dissemination of information on vertebrate pests and their control. Some things have changed in these 22 years, most of which have been for the good. The first …

Vole Control In Field Crops, Jerry P. Clark

Proceedings of the Eleventh Vertebrate Pest Conference (1984)

There are five species of meadow voles found in California. The two that are most economically important are Microtus californicus and Microtus montanus. Meadow vole populations are extremely cyclic, reaching a peak every four to six years. During these periods when the vole population is increasing in numbers, damage to crops like alfalfa, artichokes, potatoes, and sugar beets can occur. The best time to survey for vole activity is before the crop is planted. The grower or farm operator should look for vole activity in grassy borders around the crop or along roadsides and ditch bank areas. Snap-trapping may …

Performance Of Sodium Cyanide Ejectors, Guy Connnolly, Gary D. Simmons

Proceedings of the Eleventh Vertebrate Pest Conference (1984)

Performance of three models of sodium cyanide (NaCN) ejectors was evaluated at Port O'Connor, Texas, early in 1982. M-44s, M-50s, and coyote getters were test-pulled and reset at 7-day or 21-day intervals for 42 days. Each pull was recorded as good if, in our judgment, it would have taken a coyote. Based on 402 to 430 test pulls of each ejector model, the percentages of good pulls were 40% for M-50s, 73% for M-44s, and 99% for coyote getters. M-44s with shortened plungers performed better than standard M-44s.

Most pulls of M-50s resulted in ejection failure due to corrosion between …

Woodpeckers: A Serious Suburban Problem?, Scott R. Craven

Proceedings of the Eleventh Vertebrate Pest Conference (1984)

Damage to homes and buildings caused by woodpeckers is a widespread and locally severe problem in vertebrate pest control. This paper describes the distribution, characteristics, and impacts of woodpecker damage as determined by questionnaires, interviews, and published accounts. Woodpecker damage results from territorial behavior, feeding, or nesting activity. Some plywood and cedar are especially vulnerable. Average loss per incident is about $300, although some cases result in much greater losses. Disturbance and aggravation are also important factors. Abatement measures include scare devices, structural modification, chemical treatment of the siding, and shooting or trapping (with a permit). Success is variable. Recommendations …

Use Of Microcomputers To Aid Wastewater Treatment Plant Operations, David G. Parker, Sandra C. Parker

Technical Reports

This report presents the development of a microcomputer based data management system for wastewater treatment plants. The relational database model was shown to be well suited for data management applications in wastewater treatment plants. A general data management system was developed for use with a microcomputer using a commercially available relational database management system. Use of the developed system requires no special computer training. The system was tailored for use at the wastewater treatment plant at Springdale, Arkansas. The capabilities of the system were demonstrated with actual data from the Springdale plant.

Studies Of Effectiveness Of Commercial Home Treatment Systems, William W. Trigg, Raymond D. Couser

Technical Reports

Eleven home water systems were tested representing six different types of filtering systems. Tests were made for Sulfates, Nitrates, Phosphate, Iron and Escherichia coli and Enterobacter aerogenes before and after passing through a home treatment system. All of the systems removed iron adequately but had little effect on the removal of nitrates, phosphates, sulfates or control of pH. Since none of the ground waters was contaminated by coli- forms, nothing was established regarding the effectiveness of bacterial removal by these systems.

Wetlands Forest Communities As Indicators Of Flooding Potential In Backwater Areas Of River Bottomlands, Edward E. Dale Jr.

Technical Reports

A phytosociological study was made of forest types that occur in backwater and river bottomlands of the Gulf Coastal Plain, Arkansas Valley, and Mississippi Delta Regions of Arkansas. Twenty different forest types dominated principally by a single species were identified and described. Their occurrence was then correlated with flooding conditions in their habitats and the types were arranged along decreasing moisture gradients. Those forest types tolerant of flooding or saturated soils between three months to a year or more are Taxodium distichum, Nyssa aquatica, Cephalanthus occidentalis, Salix nigra, and Planera aquatica types. Those tolerant from one to three months are …

Evaluation Of Nitrogen And Phosphorus Enrichment Using In Situ Enclosure Bags With Temporal Indigenous Phytoplankton Populations, Richard L. Meyer, W. Reed Green

Technical Reports

An in situ experimental procedure and protocol was developed to evaluate nitrate and phosphate enrichment using isolated indigenous phytoplankton assemblages during different seasons. Results of the comparison of the parameters-temperature, pH, alkalinity, conductivity, and dissolved oxygen between the open water and enclosed systems indicated that there was no significant influence of the physicochemical factors on the isolated biological processes. Growth responses were measured by turbidity, biomass and chlorophyll-a, the most sensitive being chlorophyll-a. Additions of nitrate and phosphate were added in known concentrations and in different magnitudes of concentration based upon ambient conditions and ratio. During the fall, phosphorus influenced …
